Intel Core i7 For Laptops — First Benchmarks 196

Barence writes "PC Pro has benchmarked the first Intel Core i7 processors for laptops. The chips mark the debut of Intel's Turbo Boost technology, which ramps up the speed of the working cores if two or more cores are sitting unused. For the quad-core i7-820QM, this can take the stock speed of 1.73GHz up to a maximum of 3.06GHz. The 2D benchmarks show comparable performance to Core 2 Extreme chips running at 2.53GHz. Power consumption and processor temperature is dramatically lower, which should lead to significant improvements in laptop battery life."

        • by mikael ( 484 )

          I remember those - our PC's (IBM PC clones that had the monitor on top) had the Turbo Boost button that would give your PC that extra bit of oomph when you needed those spreadsheet tables calculated in a jiffy or that word processor macro processed in a hurry. It would boost the clock speed up from 8 MHz to 16 Mhz. With Later models of PC tower units, there would have a couple of LED digits that displayed the clock speed (20/25/33/40/50/60 Mhz).

          • I still have one of those cases. Sure no screw fits with the mainboard currently in use, but it's metal and the case fits so well into the table that I'd rather make a few extra holes, and cut out the parts of the case that hinder the ports rather than buying a new one.
            No idea what to do with the turbo button/led though.

            Actually, they didn't really "display" the speed. They displayed whatever the little jumpers on their back told them to display. Yeah, they were jumper controlled displays. You could set them to anything you wanted. I remember "reprogramming" one into displaying "Hi" and "Lo".

          • You have it the wrong way around. 16MHz was the native speed of the machine, but a lot of old software (games in particular) used timing loops that broke on computers that ran faster than 8MHz (the IBM PC ran at 4.77MHz, but most 8086 machines ran at 8MHz). The Turbo button existed to slow down the CPU for these games. DOSBox has a similar facility, allowing you to cap the emulated CPU speed to make these games run correctly.

      Seriously, couldn't the marketing droids come up with a better name?

      Sadly, this technology was called "Intel Dynamic Acceleration" (IDA) in Core-2 CPU's, but nobody noticed it. So, Intel tried with "Dual Dynamic Acceleration" (DDA), but again, nobody noticed. At last, renamed it to "Turbo Boost" and now everybody thinks it's something new.

      So, after three attempts, it seems that the current name is the best.

        Maybe because (from what I can tell), IDA and DDA only boosted one core by ~200 MHz or less, TFS suggests that Turbo Boost can take one core of a 1.73 GHz chip to 3.06 GHz, which is substantially better. Maybe that's why people are noticing now?

        • On desktop i7's, Turbo Boost still only gives an extra ~200MHz (albeit to all cores). I'm not sure if they actually mean the Turbo Boost on the mobile i7 chips will upclock by up to 1.33GHz, or if they just mean that the chip will be available with base clock speeds in that range.

            The new Lynnfield i-7s see a much bigger boost. My i7-860 goes from 2.8 to 3.46 gHz, which is fairly significant.

            • Interesting; my i7 920 only goes from 2.66 to just a shade under 2.8. I'd be somewhat jealous were it not for the fact that the 920 is already more processing power than my hard drive and video card can keep up with ;)

              There's no overclocking involved, I assume?

                    --- Mr. DOS

              • The TB settings on the earlier Core chips were much more conservative.

                Intel want to stay inside the rated TDP of the chip, but overclocking increases power consumption. However, unlike the older i7 series these newer chips can cut their usage down to nearly nothing when idle. As such they have more headroom for clock frequency increases.

          No, what I am saying is you can't have both without making some manner of compromise at the moment.

          There's currently no real incentive for Intel to make more energy-efficient Core 2 Duos because the market -is- very segmented between those who are perfectly fine with the Core 2 Duos as they are (fairly powerful and reasonable battery life, though not fo true mobility), and those who really need longer battery life and are on the go a lot, who are fine with a netbook using a Core 2 Solo or Atom (or any of the AMD equivalents) processor.

          Of course it -is- possible to get something in between, but you have to accept (unless you have millions to pursuade Intel otherwise ahead of any schedule they might have to introduce a more efficient platforms after all) that it is a fairly niche market.

          Companies do cater to that niche market, however; Lenovo, for example. The Lenovo T400 runs a nice Core 2 Duo. Its battery life is a bit above that of the average notebook - but you -can- even extend that by upgrading from a 4-cell (~4 hours) to a 6-cell or even a 9-cell battery (~10 hours) and go beyond that if you add the external bay battery.
          Take the figures with a pinch of the usual 'battery life claims' salt and you should still be very comfortable with the 9-cell w/o bay battery.

          No, adding batteries doesn't make the platform more efficient, but it -is- the next best thing available right now, especially if the desire is for 'longer battery life' and not necessarily a more efficient platform.

      Yep... the Turbo Boost is a great idea for desktops, it always gives you the maximum performance within a given thermal envelope. But to laptops, it's pretty much the anti-steedstep, making it spend as much power as possible when it's almost idle. However, it seems they didn't test the real minimum by disabling turbo. I'm assuming the laptops can control this from software, anything else would be silly. Sure, it'll also drop your performance from 3.06 to 1.73GHz but since power is roughly proportional with

      • Using Linux' frequency controls, the Turbo just increases your maximum multiplier by 1, and that's it. If you're configured to maximum performance, you get the Turbo, otherwise you don't.

I'm assuming the laptops can control this from software, anything else would be silly. Sure, it'll also drop your performance from 3.06 to 1.73GHz but since power is roughly proportional with frequency squared it should also lower the CPU to about (1.73 / 3.06)^2 = 32% power consumption.

        It's a good point that this seems to counter speedstep, but to some extent they work together. A 3.06 GHz frequency allows a particular computing task to be finished faster so the chip can fall back to the idle speedstep frequency (on my ~3 GHz desktop i-7 the idle speed is 1.2 GHz). Also, come to think of it, you mixed up the exponent in the CPU power equation. The power draw is proportional to frequency and to the square of voltage, not the other way around. So assuming CPU task completion time scales to the -1 power with frequency, which seems reasonable, the increased power draw for the higher frequency exactly cancels with the fact that processes will finish faster.

          When buying a computer, it's never very wise to pick a model that merely meets your expectations, or undercuts them. A computer that's only suitable "for surfing the web"and "word processing" may just happen to choke on web video.

          Even if you aren't a hardcore gamer, there's always a chance that some company might release a compelling title-- that doesn't even run on your new barebones laptop,

          Ok, so you run linux. Ever thought of tweaking the code? A faster laptop might reduce build times to the point where coding is pleasurable-- from hours to minutes.

          But you've looked at this from a architecture cynic's point of view-- there's no way that programmers will learn parallel processing, rendering a 4 core machine (like the i7) useless. That too might pass.

          It's a joke that dual core is useful for flash because one cpu can choke, and the other can make the system responsive enough to shut down the offending video. But a second or third core can be used by the OS to house clean, make backups, index files, scan for viruses, In addition, various languages and tools are emerging that make concurrent, multithreaded programming easier than before. SInce single threaded performance is not the sole focus of future CPU design anymore, programmers will have no choice but to program for multiple cores.

          Today, not six months from now, but today, Google Chrome generates multiple processes, one for each window. Might it be faster on a Core i7? Next year, to surf the web in style, you just might "need" a Core i9 with 24 GB RAM.

          I hope that answers your questions.

    • The CPU isn't the only power hungry component in a laptop, but I will stick to only talking about it for the sake of staying on topic with the article. For most people what you are asking for is accomplished by using the slower version of the current CPU. It also saves them money, so they have little to complain about. The hardcore people buy the fast CPU and force throttle it down in the BIOS.

      Having said that, I think you are asking for an expensive CPU where the development dollars are mainly focused o

If you want to browse the web and have a couple of pages open that have flash on, and have microsoft office open and listen to music at the same time, that stresses an atom. So basically everyone who goes to college needs more than an atom.

    coming to a macbook pro near you in january, i'd guess....

    • haha you're funny
    • While I wouldn't bet against it, I'd tend to doubt it.

      Apple prides itself on it's thin, lightweight, and attractive notebooks/desktops. They're not necessarily into the whole "faster is better" concept--if you're concerned with speed above all else, consider the Mac Pro.

      While I'm far from an expert, from what I can see from the graphs, these appear to run hotter than the Core 2 Duos that Apple uses now. I'm not sure that MacBook Pros can stand to get much hotter than they already are.

      Maybe you'll see them

      • The 17" PowerBook / MacBook Pro has always been the exception to this; it's Apple's luggable. A nice machine if you want something that you can move between desks easily, but not really a portable. I wouldn't be at all surprised to see the i7 in the 17" MBP.

        That said, it also depends on how far Apple wants to take ARM. They've ported their kernel to ARM for the iPhone / iPod Touch and the rest of their OS has already made one architecture transition so should have all of the CPU-dependencies ironed out

    I really like it when chips have small idle power usage, and this chip seems to run pretty cool when it is not taxed. Intel always had the lead in manufacturing capability, and it seems that this is one of the nice results.

    I'm really waiting for the day when you (can) just leave your computer on at all times. Most of the times the chips are doing nothing anyway, so why should it use any power? Where is the technology to switch off memory banks when they are not used? Just page the stuff to my SSD (yes, I'm talking about the future here). Why don't processors have a small power efficient core for running the OS and applications at idle? Gigabit ethernet is getting power saving functions as well, and Wifi N has power saving features as well. Having the computer almost idling without having the fan of my PSU or processor switch on should be a killer feature.

    One thing missing seems to be software support. I don't like it when my laptop drains much power just because one core is using 100% power because of a friggin flash ad on one of the tabs in my browser. We need more ways of restricting processes to use as many resources. What use is a computer that runs on almost no power when idle when it is never idling? And we'll need OS support for cores with different feature sets as well.

      Intel always had the lead in manufacturing capability, and it seems that this is one of the nice results.

      This time it's little to do with their manufacturing capability in terms of process size, it's R&D specifically to achieve this. They basicly created a new "shut-off" form of transistor that effectively blocks off everything behind it. You can read more about it here [anandtech.com].

    The article doesn't seem to suggest that this will really be enough to bring quad core laptops out of their current niche - we're talking an expensive machine which will clock in a bit over 3 hours battery life if you don't use its power, and potentially under an hour if you do. This would presumably be even worse with the higher clocked chip mentioned. I just don't feel there's much demand for such portable workstations - I can't see a good case for doing anything that processor intensive on the go. What does look very interesting is the 32nm dual core version - if they can carry over a comparable power consumption improvement to what they've achieved at the quad-core level that could be a very fast, very power efficient machine.
    • Gaming. I know a lot of gamers who would live with keeping it plugged in 95% of the time just to have a mobile rig with a decent framerate. Yeah, with an external mouse plugged in all the time, and the AC adapter its not going to be as portable as a netbook, but for a gamer who travels a lot, its a whole lot easier than taking a desktop + monitor on the road.

      How about pairing one of these with an Intel Atom? The atom turns on cores within the Core I7 when it is pegged, and turns them off (potentially turning off the entire chip) when things quiet down.

      • I would love to see that happen, perhaps even integrating the atom into the motherboard? I got fed up with high electric bills, so i replaced my desktop with a $300 eeepc 1005ha. Hooked up a kvm and only boot my desktop when I'm gaming. The eee can handle pretty much everything else I do and it draws less than 32 watts when in full power mode.

      • Yes, and you could actually integrate it into the north-bridge, if there still is a north-bridge of course. But there are quite a few hurdles of just integrating another processor, that has to use the same peripherals and memory. OS support would be needed as well (as I said in the posting above) since the Atom has quite a few other characteristics than an I7. That's why implementing an Atom like core into the CPU itself might make more sense. It would still be a very, very tricky thing to do.

    • I can't see a good case for doing anything that processor intensive on the go

      That isn't the only use case for such a laptop. I don't often need to use my laptop "on the go" but I do need to bring my work home with me.

      Another very interesting use is iMacs... Apple's desktop is using mobile chips to keep noise / heat / power usage down, and thus allow their compact form factor.

    From TFS:

    Power consumption and processor temperature is dramatically lower, which should lead to significant improvements in laptop battery life.

    worry not. Microsoft and Adobe will find a way to offset that....

    • What do you mean, "will find"? Adobe flash is already the single app using most of my computers power, simply because one page with a flash ad can take all the resources of a single CPU core.

        It's the ad author, who used a loop for polling or delaying until the next frame instead of a wait or sleep, who's to blame. Anyway, just run Firefox with Adblock Plus and you'll see hardly any of those ads.
        • Flashblock (or equivalent - something is available for most browsers) is even better for this - it blocks legitimate (non-ad) Flash until you want it playing. Great if you have a few tabs open to something like YouTube.

          • I'll second that. I use click2flash in Safari, which does the same thing. The company I rent DVDs from recently launched a streaming service which uses flash. This works fine on the old PowerBook I have plugged into my projector, except for one thing. Quite often, they show flash ads on the same page as the video. This uses enough CPU time to cause the main video to drop frames. Click2flash fixes that; neither starts until I click on it.

    Where is the middle? Atom based equipment is changing how we define portable computers and is very exciting. These new chips are going to bring amazing power in a portable format. The problem for the average user is that these are two extremes that currently don't help them. The middle of the road laptop that can be used for everyday use has not had any major innovations or significant price drops for some time. I understand diversifying is important, but where is the new tech for that more middle of the road work load?

Those with eSATA and HDMI connectors and high end cameras and microphone arrays? The ones with usable fingerprint reader devices?

      What about two chips? One runs when on battery mode - gives the best power savings. One that runs when the laptop is plugged into the wall for best performance.
